The PCI PIN Reporting Template requires, “For entities engaged in the processing of PIN based transaction provide a network schematic describing PIN based transaction flows with the associated key type usage.

AWS Payment Cryptography has reported the internal service structure for our PCI PIN assessment. Your diagrams will illustrate calling the service APIs for PIN processing.
